NAME

Test::Harness - Run Perl standard test scripts with statistics

VERSION

Version 3.42

SYNOPSIS

use Test::Harness;
runtests(@test_files);

DESCRIPTION

Although, for historical reasons, the Test::Harness distribution takes its name from this module it now exists only to provide TAP::Harness with an interface that is somewhat backwards compatible with Test::Harness 2.xx. If you're writing new code consider using TAP::Harness directly instead.

Emulation is provided for runtests and execute_tests but the pluggable 'Straps' interface that previous versions of Test::Harness supported is not reproduced here. Straps is now available as a stand alone module: Test::Harness::Straps.

FUNCTIONS

The following functions are available.

runtests( @test_files )

This runs all the given @test_files and divines whether they passed or failed based on their output to STDOUT (details above). It prints out each individual test which failed along with a summary report and a how long it all took.

It returns true if everything was ok. Otherwise it will die() with one of the messages in the DIAGNOSTICS section.

execute_tests( tests => \@test_files, out => \*FH )

Runs all the given @test_files (just like runtests()) but doesn't generate the final report. During testing, progress information will be written to the currently selected output filehandle (usually STDOUT), or to the filehandle given by the out parameter. The out is optional.

Returns a list of two values, $total and $failed, describing the results. $total is a hash ref summary of all the tests run. Its keys and values are this:

bonus Number of individual todo tests unexpectedly passed
max Number of individual tests ran
ok Number of individual tests passed
sub_skipped Number of individual tests skipped
todo Number of individual todo tests
files Number of test files ran
good Number of test files passed
bad Number of test files failed
tests Number of test files originally given
skipped Number of test files skipped

Set the formatter_class of the harness being run. Since the HARNESS_OPTIONS is seperated by :, we use - instead.

Multiple options may be separated by colons:

HARNESS_OPTIONS=j9:c make test

HARNESS_SUBCLASS

Specifies a TAP::Harness subclass to be used in place of TAP::Harness.

HARNESS_SUMMARY_COLOR_SUCCESS

Determines the Term::ANSIColor for the summary in case it is successful. This color defaults to 'green'.

HARNESS_SUMMARY_COLOR_FAIL

Determines the Term::ANSIColor for the failure in case it is successful. This color defaults to 'red'.

Taint Mode

Normally when a Perl program is run in taint mode the contents of the PERL5LIB environment variable do not appear in @INC.

Because PERL5LIB is often used during testing to add build directories to @INCTest::Harness passes the names of any directories found in PERL5LIB as -I switches. The net effect of this is that PERL5LIB is honoured even in taint mode.

sure is, that it was inspired by Larry Wall's F<TEST> script that came
with perl distributions for ages. Numerous anonymous contributors
exist. Andreas Koenig held the torch for many years, and then
